Right now, only the framebuffer supports this system call, to query its dimensions.

78d72c2f0c Kernel, libc: Add a getdents() system call
This is meant to be a low-level interface to implement dirent.h on top of.

da61e3648f Kernel: Implement blocking reads
This is a huge step forward!! bc actually runs now, without echo or backspace, but it runs!!

f8154ce230 Kernel: Implement mkdir() from a single path
This is done using dirname() and basename() :)
2022-10-16 14:45:25 +02:00
97b7572933 VFS: Implement a new type of Node, VFS_DEVICE
This is used to differentiate normal files from devices.

0a7d4a530d VFS, DeviceFS: Implement a device filesystem
For now, we just have a version device. (this will allow us to get rid of sys_getversion!!)
More should be implemented soon.

4aa3da8c12 VFS: Add basic mount(), unmount() and mkdir() functions (not accessible to userspace yet) 2022-10-11 18:23:00 +02:00
1278cec065 VFS: Add a 'type' flag to Nodes, implement EISDIR 2022-10-11 17:48:11 +02:00
bbe7c6e658 VFS: Implement resolve_path and form the initial ramdisk's VFS properly
Finally, resolve_path: a function which takes a path (/etc/fstab for example), and walks the VFS:
In this case, it would start with the root FS node, and ask it: "do you have a directory/file named etc?"
The node could say 'yes', 'no', or 'i'm not a directory, I'm a file' (should not be the case for the VFS root, but for the other ones it could be)
If it says yes, we continue and ask the child if it has a file named fstab. Etc...

2be70d0bc1 VFS: Use 64-bit numbers in read()
There is no need for any kind of 32-bit compatibility.
